hi mallower, they don't seem too attentive here but there is still lot's of info here, you just have to dig for it. i'm new to growing myself so i can't answer many of your questions from experience as i'm only on my second grow but i can try to help and if nothing else, i should be able to point you in the right direction. i must say though, the guy you know personally is your best source of info, first, you know him and second, he sounds like he should know his shit.
i would suggest that you do a thorough search through the FAQ's, you'll have to dig but it's worth it, get a copy of Jorge Cervantes latest book too, that guy know's how to grow.
anyway, for what it's worth, i'm here and i'll try to help if i can

peace, love, dope
